Elever med läs- och skrivsvårigheter/dyslexi : En kvalitativ studie i förskolan och i grundskolans tidigare år

This work concerns children with reading- and writing difficulties/dyslexia. My purpose is to investigate the practical experience of teachers as well as their everyday work with these children.My questions are:How do teachers work with children aged 4-9 who have reading- and writing difficulties/dyslexia?Which various teaching aids exist for children who have reading- and writing difficulties/dyslexia?Which subjects are affected by reading- and writing difficulties/dyslexia?To answer the above questions I have used the qualitative method. I have performed interviews and observations. Previous research has shown that reading- and writing difficulties/dyslexia is one of our most common disabilities.

Simulering av värmebehov för kombinerad kontors- och laboratoriebyggnad utan traditionellt värmesystem

In this Thesis the possibilities of designing a larger building that is very energy efficient in the sense that it would not need a conventional heating system are discussed. Solar radiation transmitted through the windows, internal heat from occupants, lamps and electric appliances inside the building and heat recovered from the ventilation system then have to be sufficient for the heating of the building. This study is of general interest since the property company, Akademiska Hus, plans to use this study as a first step in determining if this technique could be used in the future and thus be worth further investments. A building without a conventional heating system of the size investigated in this project has not yet been built.The energy needed for the heating of the building was simulated using VIP+.The conclusions from the study are that it is possible to build large buildings without any conventional heating system. This could be achieved in many different ways, for example by lowering the inside temperature or by using better windows and heat recovery system with higher efficiency.

Energieffektiv design av ett inbyggt flashminneshanteringssystem

The report is the result of a master thesis at ENEA AB during the fall of 2009. Itaims to create a specification of flash memory management system which focuseson power efficiency and low RAM usage for embedded systems, and to design andimplement a prototype of such a system to facilitate further development toward thecreated specification. The system used by ENEA today is a Flash Translation Layer(FTL). It has a complex structure which prohibits modifications and customization,therefore a new flash memory management system needs to be developed.The suggested solution uses a translation layer called Metadata FTL (MFTL), wherefile system metadata and userdata are separated from each other in order to improveperformance. The partition holding userdata uses a block-level mapped translationlayer system called Fully Associative Sector Translation FTL.

Kan detektorer förebygga tågurspårning?

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Vattnets väg genom en romersk stad. -Från vattenkastellet till mottagaren.

The purpose of this paper is to make an analysis of the urban Roman water system. I have chosen to work with the system as a general field, not as a case study of a single town. In my opinion such a study would not give a proper and fair view of the subject. Therefore, this paper will discuss the different parts of the system, each one for itself and name examples wherever possible, to give a wide survey of the reality of the Roman water supply system. The aim is to give the reader a clear picture of different solutions used in the time of the early Roman Empire and a good understanding of the subject..

Problemlösning ? En jämförelse mellan svensk och japansk undervisning

Det senaste decenniet har matematikundervisningen i Japan fått mycket uppmärksamhetför dess annorlunda och unika sätt jämfört med västerländska motsvarigheter. Dennaundersökning jämför matematisk problemlösning mellan Sverige och Japan. Treundersökningsmetoder användes: analys av läromedel, lektionsobservation ochelevlösningsanalys. Under de svenska lektionerna arbetar eleverna ofta enskilt medmånga uppgifter, då de samtidigt lär sig matematiska begrepp och lösningsprocedurer.På det sättet skaffar sig högpresterande elever en självsökande problemlösningsförmåga.Eleverna föredrar att använda konkreta metoder vid problemlösning. De japanskalektionerna däremot fokuserar mest på genomgångar av nytt stoff med ett fåtal problem.Klassdiskussioner om olika lösningsmetoder ger eleverna en djupare bild av problemen.Elever arbetar med algebra i större utsträckning och är vana vid att uttrycka sig påmatematiskt korrekt språk.

Utbildningens roll för nyttjandet av MPS-system

Tillverkande företag har under de senaste åren ställts inför en förändrad marknadssituation, vilket innebär att de fått förändra sitt arbetssätt från en produktionsorienterad syn till en kundorienterad syn. Den kundorienterade synen innebär att företag snabbt måste kunna ställa om sin produktion för att tillfredsställa kundens behov.MPS-system (Material- och ProduktionsStyrningssystem) är mycket effektiva hjälpmedel vid snabba beslut och omplaneringar, de ger dessutom möjlighet att ge kunder direkt besked om orderstatus. MPS-system tenderar att bli stora och komplexa, de har kontaktytor mot nästan alla delar i företagen.Många företag idag köper MPS-system. Stora företag byter gamla föråldrade system och allt fler små och medelstora företag inför MPS-system. Kommande milleniumskiftet är också en orsak till att flera företag byter sina MPS-system idag.Med detta väcktes intresset för att undersöka om företag som investerar i dyra MPS-system verkligen får ut det de förväntar sig av dem.

In order to acquire a BSc-degree in Computer and Electronics Technology at the University of Linköping I have carried out a diploma work, regarding new computer programs to fulfil the customers? wishes. The machine NMD 100 is connected to its PC through handshaking.

Prestationsmått: Ett verktyg för styrning - eller en rapport bland alla andra. Om mellanchefers tillämpning av prestationsmått i styrningen av operativa enheter.

A performance measurement system can be used as a means to evaluate past performances and to communicate prioritizations. It has also been proposed that a performance measurement system can serve as a method to execute strategies, guide in operational decisions and constitute a tool for making the organization more efficient. Yet one may question if such a system will ever reach this capacity if operating managers do not utilize it as a management tool, but rather treat it as a mere report in the bunch. This paper explores how middle managers in fact apply performance measures and what obstacles there are to integrating them in the management of subunits. Furthermore it serves to investigate whether these managers experience a conflict between how they are expected to use the measures and what they deem possible to adopt.

Bilden av kvinnan i Library of Congress Classification En genusstudie av Library of Congress Classifications första och senaste upplaga

I have done a comparative gender study of Library of Congress Classification from 1900 and 2001. I have also used a hermeneutic method and ideological critics to find out what picture of women the both systems shows. In my comparative study of the both systems I have found low update of classes which relates to women in the new classification system. Men seem to be a norm in the system, because men are not defined in classes related to both men and women. But many classes related to women are named Women as and Women in The study also shows that women are more related to subjects about family and marriage than men are.

Med datorn som följeslagare : Perspektiv på datorers inverkan för lärare i ett En-till-En-projekt

In today?s society we depend on technology to perform the simplest tasks. Whether we are engaging in conversation with a friend or are navigating in traffic, we are likely to be found with some technological device in our hands. This dependence has grown over a period of time, and many of us have failed to reflect on the impact technology has had on our lives. The emergence of so-called One-to-One projects, where teachers and students gain access to a personal laptop, does however provide an excellent opportunity to do so.

Utveckling av minimax-baserad agent för strategispelet Stratego

Stratego is a boardgame not very different from chess, that contains hidden information. Because of this, existing programs play at beginner level. The purpose of this thesis is to adjust a minimax algorithm so that it passes the demands of Stratego, and then build a Stratego agent around it. Tests with existing minimax algorithms leads to the development p-e-minimax. This algorithm uses two different values in its nodes to simulate the different information available to the agent and its opponent.

Användarinvolvering vid systemutvecklingsprojekt i vården

Vårdsektorns IT-system fungerar inte optimalt ur användarsynpunkt då acceptansen bland de olika professionerna är låg.  När IT-systemen inte klarar av att stötta vårdaktörerna i deras dagliga arbete så kan det medföra en rad olika följder så som stress, tidsbrist och minskad patientsäkerhet. Därför ser vi att IT-systemen bör utvecklas ut användarsynpunkt för att klara av att fylla sin funktion som ett hjälpmedel i vården. Denna uppsats ämnar undersöka hur användarinvolvering vid systemutvecklingsprojekt i vården kan utvecklas. Genom en intervjustudie så kartlades den nuvarande situationen i vården. Med detta som utgångspunkt har vi sedan föreslagit tekniker och verktyg som kan hjälpa leverantörer och beställare att förbättra användarinvolveringen vid implementering av nya IT-system i vården.Nyckelord; IT-system i vård, användarinvolvering, Participatory Design, systemutveckling.

Två olika tårsubstituts påverkan av synkvaliteten

Tårsubstitut används mycket bland linsbärare och personer med torra ögon. Detär vanligt nuförtiden att arbete i kontorsmiljö och vid datorer ger problem medtorra ögon, Computer vision syndrome (CVS), och att dessa personer dåanvänder tårsubstitut. Ofta står det i tårsubstitutens bipacksedel att de kan geproblem med dimsyn en stund efter applicering.Tidigare studier har visat att aberrationerna i ögat ökar vid applicering avtårsubstitut och möjligtvis är det anledningen till att dimsynen uppkommer.Syfte: Syftet med studien är att ta reda på hur mycket synkvaliteten påverkas avtvå olika tårsubstitut och hur lång tid den påverkas.Metod: Metoden innebar att närvisus och aberrationer mättes på 30 patienter (60ögon) först utan tårsubstitut. Sedan applicerades det första tårsubstitutet(Systane) i höger öga och ytterligare en mätning av närvisus och aberrationerutfördes. Därefter gjordes ytterligare 5 mätningar av aberrationerna, en var fjärdeminut.
